    For this case what you should do is the following system of equations:
     x: skilled laborers
     y: unskilled laborers
     By writing the system we have:
     x + y = 24
     25x + 12y = 405
     Solving the system:
     Step 1:
     -25x + -25y = -600
     25x + 12y = 405
     Step 2:
     -13y = -195
     y = 195/13
     y = 15
     step 3:
     x = 24-y
     x = 24-15
     x = 9
     Answer:
     skilled laborers = 9
     unskilled laborers = 15
